索绪尔与罗宾·雅柯布森同为在语言学发展史上具有重要影响的语言学家。索绪尔的语言学思想对罗宾·雅柯布森产生了极大影响,在其之后学术生涯里,罗宾·雅柯布森在继承索绪尔普通语言学理论的基础上,针对相关的理论提出了修正和发展,其中尤以其对索绪尔共时和历时的语言研究方法的修正颇为重要。本文正是希望通过比较罗宾·雅柯布森和索绪尔对于语言共时历时研究的差异,进而能够正确理解共时历时这一对语言学中重要的概念。 Saussure and Robin Yakobson are both linguists who have an important influence in the history of linguistics. Saussure’s linguistic thinking had a great influence on Robin Yakobson. After that, in his academic career, Robin Yakubson inherited Saussure’s general linguistic theory, Theories put forward amendments and developments, of which the revision of Saussure’s synchronic and diachronic linguistic approaches is of particular importance. This article aims to correctly understand the important concept of synchronic diachronic linguistics by comparing the differences between Robin Yacobson and Saussure in the study of language synchronic time.
